Description

NightSight™ is a comprehensive vision formula designed to support healthy eyesight throughout the day — and especially in low-light conditions.*

As we get older, many people begin to notice changes in how their eyes perform — particularly at night. Headlights may feel brighter, road signs harder to read, and it can take longer for your eyes to adjust when driving after dark.

These changes are often related to how the eyes respond to light, glare, and contrast — especially in low-light environments.

Formulated with clinically studied ingredients, NightSight™ helps support visual clarity, supports low-light visual performance, and helps the eyes adapt to changing light conditions — so you can feel more confident navigating both your day and your night.*

Helps Support Visual Comfort During Daily Screen Use* —Supports eye comfort during prolonged screen time and everyday visual demands
Supports Contrast Sensitivity* — Helps distinguish objects more clearly, especially in low-light or nighttime settings

NightSight™ Healthy Vision Formula

Why Driving at Night Feels Different Over Time

For many people, the first noticeable changes in vision don’t happen during the day — they happen at night.

Headlights may feel more intense. Road signs may seem harder to read. Your eyes may take longer to adjust when moving between light and dark.

That’s because, as we age, the eyes can become more sensitive to glare and slower to adapt in low-light environments.

These changes can make nighttime driving feel more stressful and less comfortable than it once did.

NightSight™ is designed to support your eyes in these moments — helping support visual performance when lighting conditions are at their most challenging.*

So you can feel more confident on the road, out at night, and in any low-light setting.

Targeted Ingredients for Day + Night Vision

NightSight™ combines clinically studied ingredients selected to support how your eyes perform in real-world conditions — from bright daylight to low-light environments.

150 mg

European Black Currant Extract

Provides anthocyanins studied for their role in supporting dark adaptation and low-light visual performance.*

10 mg

FloraGLO^® Lutein

Supports retinal health and helps filter blue light exposure during the day.*

2 mg

OPTISHARP^® Zeaxanthin

Supports visual clarity and helps the eyes respond to bright light and glare.*

Science That Supports Low-Light Vision

Your ability to see clearly — especially at night — depends on how well your eyes respond to changing light conditions.

Ingredients like lutein and zeaxanthin have been studied for their role in supporting macular pigment density and visual performance — both important for maintaining clarity in both daylight and nighttime conditions.*

Because better vision isn’t just about what you see — it’s about how your eyes perform across every lighting condition.

A miracle for me

A friend told me about Night Sight, and after only four days I could SEE and DRIVE AT NIGHT! I was so excited that when I got to Target that night I started to cry. I could read the road signs! Glare from headlights didn't bother me as much! I have been taking this for four years now and will never be without it. It works!!!!!!!

Frequently Asked Questions

How is NightSight™ different from a regular eye vitamin?

Most eye formulas focus only on general vision support. NightSight™ is specifically designed to support vision in real-life situations — like driving at night, recovering from glare, and adjusting to low-light environments.*

Can this help with night driving?

NightSight™ is formulated to support visual performance in low-light conditions, including glare recovery from headlights and contrast sensitivity — key factors that can impact nighttime driving.*

How long does it take to notice results?

Results can vary, but with consistent daily use, many people begin to notice improvements in visual comfort and performance over time.*

Can I take this if I use screens a lot?

Yes — NightSight™ helps relieve occasional eye fatigue from everyday screen use, making it a great addition to your routine if you spend time on computers or devices.*

Is NightSight™ safe for daily use?

NightSight™ is designed for daily use and made with clinically studied ingredients. As always, follow the suggested use and consult your healthcare provider if you have specific concerns.

"I spend my work day in front of a computer and my off hours cooking or working on projects, and have been having more difficulty adjusting near/far focus in the past few years, and thought this was worth a shot. I take these with my morning multivitamin, and though I started off somewhat skeptical that there would be a noticable difference, I did notice better clarity and less glare at night after only a few days. I won't be throwing away my contacts or reading glasses but I'm pleasantly surprised with this supplement."

— Tom (5/5)

Awesome product for reducing eye strain / fatigue!

"I admit I was skeptical ordering this but struggle with seeing well at night and with my bifocal contacts, eye fatigue and strain is a major problem. I was incredibly amazed at how well this works! I had to come here and tell others because this is worth the money! A great product that does exactly what it says. I now can drive at night so much easier and my eyes don’t get tired when driving or reading like they used to. Awesome product!"

— Scott (5/5)

Solid supplement

"I’ve been happy with this supplement so far. The capsules are easy to take, and the ingredients seem thoughtfully selected for eye health. The product arrived fresh and well-packaged, and the quality meets my expectations. Overall, it seems like a good product, and I’m looking forward to continuing to use it."

— Dadman (5/5)

blurry halos

"I have been having some issues with glare while driving at night. I have been taking these for about 3 weeks now, and I have noticed a difference in the sharpness of sight at night. I was a bit skeptical about these at first, but the supplement definitely seems to reduce the glare or "halo" around objectas while driving at night."

— Dave (4/5)

Low Light Benefits

"Night driving has always been one of those situations where I notice my eyes working harder, especially with oncoming headlights, glare, and constantly adjusting between bright and dark areas. That’s what initially made me interested in NightSight. I really like that this formula is designed to support visual performance during both daytime and low-light conditions, rather than focusing on just one aspect of eye health. It supports healthy vision and visual clarity day and night, including the eyes’ natural response to things like glare, headlights, screens, and rapidly changing light conditions. I was especially interested in the low-light benefits. The formula is designed to support nighttime visual performance and contrast sensitivity, which can help with distinguishing objects more clearly in darker environments. As someone who drives at night, those are benefits that are genuinely relevant to my everyday life. I also appreciate that the formula includes ingredients that have been clinically studied for eye health and visual function. It’s one capsule a day, easy to add to my routine, and feels like a really simple way to be more proactive about supporting my eye health."

— Shaun P. (5/5)

Helps me see better on the computer

"I definitely noticed a difference. I work nights and I’m on a computer pretty often."

— Steve C. (5/5)

So far its worked

"I work overnights and I have seen an improvement of my night sight. Headlights aren't as blinding as they use to be"

— James (4/5)

Support for Night Glare

"I spend a lot of time driving, including early mornings, late evenings, and Florida rain storms, so I decided to give NightSight a try to support my vision as I get older. After taking it consistently, I’ve definitely noticed improvements in visual comfort, especially in challenging conditions. Much less eye strain. One thing that stood out to me was driving at sunset and during a heavy rains, situations where glare and reflections normally bother me quite a bit. Everything just seemed clearer and less straining on my eyes. I’ve also noticed less discomfort from headlights while driving at night. It's one of those things that after the drive you realize that the drive was easier and the strain wasn't there. I’m realistic, this isn’t some miracle overnight change, but I do feel like my eyes are handling low-light conditions and glare better than before. That alone has made it worthwhile for me. Easy to take and now part of my daily routine."

— Keith (5/5)

A miracle for me

"I have always had poor night vision. It was so bad that I'd go to a new location in the daytime so I wouldn't get lost when driving there at night. A friend told me about Night Sight, and after only four days I could SEE and DRIVE AT NIGHT! I was so excited that when I got to Target that night I started to cry. I could read the road signs! Glare from headlights didn't bother me as much! I have been taking this for four years now and will never be without it. It works!!!!!!!"
